Analysis was conducted for purposes of defining provenience of the raw material for three ceramics types: domestic, black-on-red, and Emir grey wares selected from Periods I and II at Hili 8 settlement and Hili North Tomb A on the Oman Peninsula of the 3rd millennium B.C. Combined thin section petrography and neutron activation analysis indicated that the domestic and black-on-red fine wares conform to the geological setting of the Oman Peninsula and the Emir grey ware probably comes from SE Iran. The cultural implications are discussed.
